Hourly billing and timesheets are inextricably linked: you cannot discuss one without the other. The reason is because both use a common measuring device: Time. There are four primary defenses of timesheets: 1. They are a pricing tool: 2. They are a cost accounting tool: 3. They are a project management tool: and 4. They measure the productivity of our professionals.

After all, he who says A must also say B. Join Ed and Ron as they falsify all of these defenses.
